Abstract

Abstract : Adsorption of benzene, chlorobenzene, and naphthalene on commercially available granular activated carbon (GAC) and bimetallic nanoparticle (Fe/Pd) loaded GAC was investigated for the potential use in active capping of contaminated sediments. Freundlich and Langmuir linearizations were both applied to this data, and it was found that the Freundlich model most closely fits the experimental data. Based on Freundlich parameters, the effective partitioning coefficients (L kg −1 ) taking into account K F and n were calculated to be 2.97 × 10 6 and 8.25 × 10 5 for benzene and chlorobenzene, respectively, on GAC. In addition, effective partitioning coefficients (L kg −1 ) were 650, 5640, and 1.91 × 10 5 for benzene, chlorobenzene, and naphthalene, respectively, on Fe/Pd/GAC. Values of log K F ( ( μ g / k g ) / ( μ g / L ) n ) were 6.11, 7.11, and 7.54 for benzene, chlorobenzene, and naphthalene, respectively, for GAC and 4.53, 5.47, and 5.22, respectively, for Fe/Pd/GAC.
